Abstract/OtherAbstract:
This study was conducted to determine the effects of Phellinus linteus (PL) on serotonin synthesis in the brain and on the expression of monocarboxylate transporters (MCTs) in muscles during exhaustive exercise in rats. In this study, 60 male Sprague-Dawley rats were divided into the following 6 groups: control; exercise; exercise and 50 mg/kg of PL treatment; exercise and 100 of mg/kg PL treatment; exercise and 200 mg/kg of PL treatment; and exercise and 100 mg/kg of caffeine treatment. Treatment with 200 mg/kg of PL led to a significant increase in the time to exhaustion in response to running on a treadmill and a significant decrease in 5-hydroxytryptamine synthesis and tryptophan hydroxylase expression in the dorsal raphe of rats. MCT1 and MCT4 expression of the gastrocnemius muscles was also increased in response to treatment with 200 mg/kg of PL. The results of the present study demonstrated that the administration of PL increased endurance exercise performance through inhibition of serotonin production in the brain and increased the expression of MCT1 and MCT4 in muscles. These results suggest that PL exerts an ergogenic effect.
